    Update - the 550 drill motor worked a treat on the 16.4v . I didnโ€™t push it too hard and it still got pretty hot. I think 8.4v will be sufficient so thatโ€™s my next test.
    Turns out these old boats arenโ€™t made from the best materialsโ€ฆ.. the skin is leaking around the keel โ˜น๏ธ which means the old circ 1960 ply is now wet inside my new paint. I should have epoxied it .

    Yes , want it to go much faster - at least on the plane . I have wired up a 550 mabuchi motor from a 12v drill but i need to make sure i donโ€™t cook it with the 16.4v

    If I run a stock 12v 550 motor on 16.8v but at say 70% max throttle will I still cook the motor ?

    Sea trials were a little underwhelming sadly . I have grossly underestimated the rpm of the traxxas titan 775 on 16.4v being 7,000rpm .
    The result is a poultry speed as you can see.
    So itโ€™s back to the drawing board ๐Ÿ™„

    I need to find a 775 motor that can spin the 40mm prop much faster on 16.4v and get it on the plane at least.
    Any ideas welcome .

    Just the windows to go in and itโ€™s ready for sea trials. Iโ€™m going to try and cut up old cd cases unless anyone has better ideas for windows .
    The traxxas 775 on 16.4 volts sounds very โ€œtameโ€ so Iโ€™m hoping I havenโ€™t got a too low rpm set up . It has a 40mm prop

    Thanks for your comment- a little secret is that the stripe is automotive min stripe ! Much easier and cleaner than painting and gives you a very clean edge. Also covers up an paint bleed ๐Ÿ˜

    Sharing a progress update on this sea rover.
    I picked this boat up last year very cheap not knowing what Iโ€™d do with it.
    Its had a long 60-70 year life and at least two different colours being orange then navy - now blue and various engines from ic to electric.

    It hasnโ€™t been built to a high standard so Iโ€™m having to work with what I have but Iโ€™m really happy with the colour - it was nearly bottle green but i changed my mind last minute . I had to build the rear roof as well as replaced the gunwale and installed a chine rail too.
    One concern is the bilge has not been water proofed or sealed which can only be accessed by major surgery.

    The motor Iโ€™ve selected is a traxxas 775 titan swinging a 40โ€prop . Not sure if I will need 16.8v to get it moving which is what the motor is rated too.

    Cheers

    Can anyone help with replacement gears for the aquacraft ep-1 outboard.
    Sadly Iโ€™ve worn mine out. They are made out of brass which isnt ideal. Manufacturing ceased a long time ago unfortunately.

    Thanks for the help on this page I added the spray rails and it has made an amazing difference. The boat sits higher handled better and stays dry. The Johnson 970 connected to a 12v sla gets extremely hot still to the point it will burn skin to touch.

    Here you go - Iโ€™m really Happy how it runs - it does sit low and the battery is too heavy but it also helps cut the water nicely. Scale speed is pretty close .
    Only issue is it got quite hot and only running a 2ah lead acid with the evx2 it didnโ€™t run long at all . Cheers all

    Maiden voyage today - the speed controller I have selected over heated and it never got on the plane so Iโ€™m going to wire up the traxxas evx2 which can handle bigger draw. I just need to remember how to โ€œshot circuitโ€ one of the power inlets so it can run of the 12v lead acid.

    Yes that battery is a bit heavy โ€ฆ.

    Need some deck fittings. Selec have them but the postage to
    Australia is ยฃ17 which is the same price as the 3d printed parts .

    Iโ€™m considering Getting a 3d printer but I know nothing about them . If I do get them are the files downloaded and press print ? Is that how it works?
    I canโ€™t seem to find many options online .
    Alternatively if someone wants to print them for me Iโ€™m happy to pay .
    Cheers

    I used everyoneโ€™s advice to get to this stage today - I went with 3 rails and removed the paint to stick them down . Soaked and steamed some .
    Still need to trim the lower ones where they meet in the middle - not sure how Iโ€™m going to finish them if I fair them flush with the hull .

    These rails are Australian hardwood and were very difficult to work with . My fingers are full of splinters and ca glue but Iโ€™m happy ๐Ÿ˜Š

    Yes - mine is 33โ€. I think the rails need to be made from brass so they can be soldered . I tried soldering a coat hanger wire - didnโ€™t work.

    Thanks for this - I think I will take your advice and do 3 to keep it looking cleaner . So far Iโ€™ve wasted about 6m of hardwood for the gunwales and chine strips snapping but Iโ€™m done now ๐Ÿ˜Š
    Side note where is a good place to get all the fittings for the deck ?

    So do these spray rails look right to you ?
    Sanded back 35 years of paint today and decided to add spray rails. Iโ€™ve been snapping timber strips all day - whatโ€™s the secret to bending these around the gunwale and waterline ?

    I have an a swordsmen built late 80โ€™s and itโ€™s never had spray rails or gunwales. Consequently it sits quite low under way.
    What is the best way to fit these and what distance off the keel are they supposed to be. I thought about using styrene but also have some hardwood but it might not bend the way itโ€™s needed to.

    Made some progress - have since bolted the outboard on and with a 12v lead acid I think might be too heavy . I will give it a try once itโ€™s all wired up and see how it runs. Iโ€™m absolutely winging this build ๐Ÿ˜€

    Hi everyone. I started this cabin cruiser 10 years ago and decided to blow the dust of recently . Itโ€™s my own design from scratch and Iโ€™m completely winging it as I go. The idea is for it to be a knock about model that I can use with my 6yo son . Iโ€™ve designed it with high freeboard to be used in choppy water and I have an ep1 outboard that Iโ€™m going to bolt on the back . โ€ฆ.. I might go for twins but that could be ambitious for a 28โ€ model . Keen to see how others have built the outboard well area and steering set up. Cheers

    I restored the same boat recently and installed two mabuchi 775 brushed motors via a single cheap eBay 480esc and 12v lead acid battery. Props are 50mm and it really moves however I had to add water cooling as I over heated one of the motors. Run time isnt that great though - maybe 10 mins . If you understand brushless and have the budget then that is the way to go I think. I didnโ€™t want to spend much and donโ€™t use it enough to justify the cost of brushless. I pulled the motors from an old hitachi drill!

    Hi all - finally got to sea trial this today . The most notable issue is shaft alignment which is why it sounds like a two stroke engine . The 5mm shafts are very old and have some pitting in the metal which is strange. There is a small amount of play with them which Iโ€™m guessing is causing the noise . The motors are cheap 700 size drill motors from eBay which do the job I think. Props are 45mm but I couldnโ€™t find counter rotation in 5mm props so they are the same which isnโ€™t a big issue.

    Turning circle is terrible and it wants to nose dive even though the lead acid battery is towards the aft. Looking at other models of this boat it seems to be common though ? Is it normal to have the props and rudders a fair way apart as per the pictures?
    I restored this model so I donโ€™t know itโ€™s history or age - it has definitely been built by an amateur and was possibly petrol powered once. Iโ€™m guessing itโ€™s from the 1970 era .

    Overall itโ€™s a great boat and Iโ€™m happy with it .

    Thanks for this info but I couldnโ€™t find any 5mm - they are 4.8mm surely they are not the same ? Anyway I will have a look at drilling out a 4mm and using a lock nut . My concern drilling is getting it out of centre as I donโ€™t have a drill press.

    Hi - I have the motor thatโ€™s in the pictures I posted - it has similar specs to a graupner 700 but is out of a leaf blower ๐Ÿคฃ.
    I found an m5 45mm prop but not a counter rotation option so I will ha e to see how it goes with two right hand rotations . Anyone noticed much prop walk/ torque issues here ?
    As a back up I have also purchased two 5mm to 4mm shaft couplings which are designed for motor to shaft applications but I might try and adapt them to the prop end by cutting an m4 screw for the prop end and attaching the prop that way if the props I have ordered donโ€™t work.

    Thanks for your help - itโ€™s greatly appreciated
    Cheers

    Thanks Doug - I am running raboesch on my other model amd they are the best but this boat swinging 60mm props are going to be too big for 700 size motors I think.... ?
    How do you go about re-bushing the shaft ? That might be a good option .
    Appreciate your advice -very helpful

    Hi all

    Im getting close to finishing restoring this monster and im stuck with a few questions that I hope you can help with.

    1) have have two 700 size motors which I want to run through a 480 amp esc with a 12v battery. Will that get it planing ok on 45mm props? am I going to blow it up?

    2) the old boat has 5mm (M5) shafts and i cannot find a 5mm prop to go on the shaft. I dont have a lathe is there another way to reduce the props shaft to M4

    3) Does anyone know where one can get 5mm (m5) props.

    Cheers

    Hi gents
    I too have the same boat and have the same question . I only have shafts and rudders so I am looking for the whole package. I know little about brushless too but I think a boat like this needs them. From the research I have done I can see 880kv twins with 2 60 Amp water cooled esc will
    Work. I would
    Like to know what brand motors I need and what prop sizes to and esc brand to get. Iโ€™d like 20 min run time too.
